You just need to mix up the broad stock. Wild salmon come in, selected for broad stock. Those hatchery produced stock return years later and majority spawn as Wild returns. Its not a reason to worry. Aquaculture industries rely on the collapse of wild salmon to promote themselves. Especially in BC where they should never be allowed to farm. Maybe wrong forum topic to be posting here. But since it was hijacked, it gets tiring listening to anti-hatchery sentiment. ie: steelhead recovery has been crucial to sustain native genetics to SVI rivers, of course you want them to be able to start rearing in the wild in greater numbers, which I agree habitat rehab is crucial while hatcheries sustain existence.
